Methods for living guidelines: early guidance based on practical experience. Paper 1: Introduction

Objectives: To introduce methods for living guidelines based on practical experiences by the Australian Living Evidence Con-sortium (ALEC), the National Institute of Health and Care Excellence (NICE), and the Infectious Diseases Society of America (IDSA), with methodological support from the US Grading of Recommendations, Assessment, Development and Evaluations (GRADE) Network.Study Design and Setting: Members of ALEC, NICE, and the US GRADE Network, convened a working group to share experiences of the methods used to develop living guidelines and outline the key differences between traditional and living guidelines methods. Results: The guidance includes the following steps: 1) deciding if the guideline is a priority for a living approach, 2) preparing for living guideline development, 3) literature surveillance and frequency of searching, 4) assessment and synthesis of the evidence, 5) pub-lication and dissemination, and 6) transitioning recommendations out of living mode.Conclusion: This paper introduces methods for living guidelines and provides examples of the similarities and differences in approach across multiple organizations conducting living guidelines. It also introduces a series of papers exploring methods for living guidelines based on our practical experiences, including consumer involvement, selecting and prioritizing questions, search decisions, and methods decisions.(c) 2023 The Authors.
